FIELD OF THE INVENTION

[0001] The present invention relates to chair backrest and moreparticularly to a backrest pad with height adjustment characteristics.

BACKGROUND OF THE INVENTION

[0002] Pads provided on parts of a piece of furniture (e.g., chair) arewell known. It is also known that various backrest pads have beenutilized throughout the prior art to fulfil consumers' needs. Asunderstood that the resiliency of backrest pad can give a degree ofcomfort to the back of a person seated on the chair. The invention hasresulted from efforts to develop an improved backrest pad for chair thatcan be adjustably vertically positioned relative to the backrest.

SUMMARY OF THE INVENTION

[0003] It is therefore an object of the present invention to provide abackrest pad for chair having a backrest including two stiles and twoopenings each enclosed by stile and backrest. The backrest pad comprisesa transversely extended member having an arcuate projection filled withsoft material facing front; two side catches; two channels each adjacentcatch; and two elastic straps having one ends stitched to channels forpermanently fastening In assembly place backrest pad onto the backrestwith straps rearward passed through the openings, and wrap straps aroundthe stiles to fasten at the catches. The backrest pad can be adjustablypositioned relative to backrest by pulling backrest pad and strapsvertically.

[0004] The above and other objects, features and advantages of thepresent invention will become apparent from the following detaileddescription taken with the accompanying drawings.
